Title (EN) OPTICAL COMMUNICATION METHOD AND OPTICAL COMPONENT USED IN THE METHOD, AND OPTICAL COMMUNICATION DEVICE COMPRISING THE COMPONENT
(FR) PROCEDE DE COMMUNICATION OPTIQUE ET COMPOSANT OPTIQUE UTILISE DANS CE PROCEDE, ET DISPOSITIF DE COMMUNICATION OPTIQUE CONTENANT CE COMPOSANT
Abstract: front page image
(EN)In the field of optical communication using an optical fiber for communication transmission line, it has been conventionally difficult to use an optical fiber practically put in use for high-speed long-distance communication at, e.g. 40 Gbps mainly because of dispersion in an optical signal transmitted through the optical fiber, and the security has been not effective. An optical communication method for transmitting an optical signal through an optical fiber after imparting dispersion to the signal using an optical dispersion imparting element comprising a multilayer film or a compensating element and compensating for the imparted dispersion or the dispersion produced in transmission so as to allow the signal to be received accurately even in high-speed long-distance optical communication, an optical component, and an optical communication device comprising the component are disclosed. Especially, the third-order dispersion is significantly effectively suppressed and compensated for. Before an optical signal is inputted to a transmission line, the signal is subjected to dispersion appropriately to enhance its security.
(FR)Dans le domaine de la communication optique utilisant des fibres optiques pour les lignes de transmission de communications, il est généralement difficile d'utiliser des fibres optiques pratiquement mises en exploitation pour des communications longues distances à grande vitesse à 40 Gbps par exemple, essentiellement à cause de la dispersion qui se produit dans un signal optique émis par fibres optiques, la sécurité n'étant pas effective. Cette invention concerne un procédé de communication optique permettant de transmettre un signal optique par fibres optiques après application de la dispersion au signal au moyen d'un élément d'application de dispersion optique comportant un film multicouche ou un élément de compensation, et après compensation de la dispersion appliquée ou la dispersion produite au cours de la transmission afin de permettre la réception correcte du signal même dans des communications longues distances à grande vitesse, un composant optique, et un dispositif de communication optique contenant ce composant. Plus particulièrement, la dispersion du troisième ordre est efficacement supprimée de manière significative. Avant l'injection d'un signal optique dans une ligne de transmission, on soumet correctement ce signal à la dispersion pour améliorer sa sécurité.
